FIELD: power engineering.
SUBSTANCE: group of inventions relates to the field of power engineering - hybrid piston internal combustion engines and engines with external heat supply. The essence of the inventions lies in the fact that a hybrid engine contains at least one stepped cylinder with a head and a bottom, which includes a constant-volume exhaust gas afterburner, two adjacent thermal working chambers (overpiston with heat supply and subpiston internal combustion) and two adjacent antiphase working chambers air compressor chambers formed by double-sided stepped pistons through the inter-piston skirt, and also separated by a heat insulator, a heater made in the form of an inner jacket of the cylinder, and a refrigerator in the form of an outer jacket, connected by a tangential channel with a thermal over-piston chamber; a displacement cavity made in the form of a hollow shell and located between the heater and the refrigerator. In this case, the channels of exhaust gases from the combustion chamber are placed in the body of the heater in the form of a hollow shell, which is the afterburner chamber, and its bottom in such a way that allow the piston to carry out slide valve timing using channels located in it, including a separate air supply channel. The use of an in-crankcase cavity as a cylinder bottom makes it possible to convert the movement of the pistons into rotation of the shaft using a rodless or crank mechanism. The supply of plasma-forming energy for activating the working gas and the use of aerodynamic air / combustible valves help to improve the energy performance and simplify the hybrid engine.
EFFECT: technical result is an increase in the specific power of the engine, an increase in efficiency, reliability and service life, as well as an improvement in environmental parameters.
